Empty Tables using Softwise SAP Connector

All,

I am new to SAP but am a very experienced .NET developer. My client wants to build a ASP.NET 2.0 web portal that integrates directly into SAP, but of course the SAP.NET Connector doesn't work with VS2005. I did find, on this forum, a product by a company called Softwise in Argentina that created an updated version of the SAP Connector. This product is able to query my SAP server, return a list of BAPI's and build proxy objects for these BAPI's. My problem is that I'm only getting part of the answer.

The BAPI that I'm calling takes some simple input parameters (dates) and has on output parameter of Return2, plus some Input/Output Table objects. The output parameter of Return2 works correctly and I can see the appropriate messages, but two of my table objects are supposed to have data in them, but they keep coming back empty.

Anybody have any experience with this tool? If so, how successful has it worked. Has anyone seen this type of behavior with the original .NET Connector?
